TROLLEY.

To NZZ whom it may concern.:

Be it known that l, @mannen A. Gower, a citiyen ot the United States.residing at Springfield. in the county ol. Sangamon and State otillinois, have invented a new and useful rllrolley` ot which thefollowing is a specification.

This invention relates to trolleys such as are used in operatingelectric cars.

lhe purposes of the invention are: to pro vide means tor mounting thetrolley wheel on the harp so that the wheel may have slight transverselyoscillative movement between the 'torks of the harp; to provide means toyieldingly support the trolleysha'ft and keep it itrom turning; toprovide means to `prevent lateral displacement ot the trolley shaftsupports; to provide simple and etl'ective means tor connecting with thetrolley harp the means it'or preventing displacement ot thetrolley-slnitt supports; and to provide lubricating washers contactingwith the ends ot the hub o'tl the trolley wheel.

The invention is illustrated in the annexed drawing to which referenceis hereby made and is hereil'ia'tter particularly dcscribed and finally`recited in the claims.

Figure l is a side elevation ot the trolley; Fig, is an oblique sectionon the line X. X. ot Fig. l; Fig'. S is a vertical section through thetrolley on the zig-zag line Y. Y. ot Fig. Q; Fig. lis an enlarged planof one ot the contact washers; Fig, is a vertical section on the line Z.Z. olf Fig. ft; Fig. G is an isonietric view oil' one ot the contactsprings and one of the contact washers in operative relation to eachother: and Fig. 7 is an enlarged isometric view of one ot the blockssupporting` the trolley shaft.

Similar reference numerals and characters designate like parts in theseveral views.

rlhe trolley harp 'l has a cylindrical stem l. adapted to turn in anysuitable support', and torkanembers ll supporting the trolley sha'tt 2,so that the trolley wheel 3 will rotate between the fork-members it. Theinner lwalls ot the it(ni'k-n'lcinbers l1* are inclined or unifier-cutas at 1L', in order that when the trolley wheel oscillates transversely.as indicated by dotted lines in Fig. 2, the rim ot the wheel will notrnb on the sides of the Jfork-1nemloers. The fork-members 1b haverectangular openings ld accommodating the blocks t and the springs 5,

and rectangular openings l accommodating the lugs tl ot the washers (i.Each ot.3 the blocks 4l. has curved 'laccs 4L adapted for rockingcontact ol the 'faces ot' the, block with the inner face oli' the guardplate 7 on one side ot the block and the inner 'face of the, contactspring l() on the other side o'ti the block. so that the block may havelimitedl lateral oscillating movement between the contact spring and theguard-plate. Finch block =t also has a lown\\'ardly extending finger 4".Elliptical coiled springs 5 fit within the openings l. and surround thefingers Ll-b o't5 the blocks t and normally act to keep the blocks in avertical position. Each o'tf the contact springs l() is shaped toconform to the inner wall o'l the harpmembers and has a lengthwise slot'10 ac commodating the cylindrical part oitl the shaft Q so that thelshat't will slide upward and downward in the slot. and a holeaccommodating a boltI 8 which connects the 'contact spring and the guardplate 7 with the 'fork-member lb.

Bolts 8 extend through the contact springs '10. the fork-memiars 1l andthe guard [dates 7. Milled nuts 9 fitting on thc bolts S, securelyconnect the parts together in such position that the cylindrical part otthe sha'tt 2 will extend through the fork 10a o't' one ot' the springsl() and through the holes -fl-C ot the blocks 1t; and the flattened part2 ot the shaft will occupy the opening 7 off one guard plate 7 and willkeep the shaft 'from turning. Flat springs l2 maintain electricalconnection between the blocks 1t. and the harp-memlmrs l." and preventrattling of' the parts. lashers ti fit around the shaft 2 andrespectively contact with the ends ot the hub ol the trolley wheel andwith the contact springs 10. and the springs hold the washers in contactwith the hub and the lugs (3 fittingl in the openings 'IP preventturning ot' the washers. Pockets (3" in the washers (l are filled withgraphite G, or equivalent lubricating n1ate rial, and the ends o'l thehub ot the trolley wheel rotate in contact with the lubricating fillingso'l the, pockets.

Tn practical use lateral pressure ou the trolley wheelv such as iscaused by the contact ot' the wheel with the trolley wire when roundinga curve. compresses the spring 5 supporting the block 4 on which ismounted that end of the shaft 2, which is inside of the curve, so thatthe wheel inclines laterally, as indicated by dotted lines in Fig. 2, toconform to the curve and thereby avoids running oftp the wire. When thecurve has been passed the spring acts to raise the block to restore thetrolley wheel to its original position.

In practice it is found that the lateral oscillations of the trolleywheel are so sudden that there is great danger of displacement of theblocks a and the springs 5. I therefore provide the contact springs l0on one side of the blocks and the guard-plates 7 on the other side ofthe blocks, said guard plates and contact springs being connected withthe harp-members so that the blocks may have limited oscillativemovement between the guard-plates and the springs, and the guard-platesand springs will prevent lateral displacement of the blocks.

To avoid unnecessary complication in construction the parts are soconstructed and arranged that a single bolt S connects one spring andone guard plate with each member 1b of the harp; and in addition toserving as guard plates to prevent lateral displacement of the blocks 4Land springs 5, the plates 7 serve to prevent turning of the trolleyshaft but permit upward and downward movement thereof.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent is:

l. ln a trolley, the combination of a harp having` members provided withtransverse openings adapted to accommodate movable blocks;shaft-supporting blocks mounted to slide and oscillate in the openingsin said harp-members; springs supporting said blocks respectively; ashaft mounted in said blocks and having a flat part; and guard platesconnected with said harp-members and adapted to prevent excessiveoutward movement of said blocks, and having slots adapted to accommodatethe flat part of said shaft to prevent rotation of the shaft.

2. In a trolley, the combination of a harp having members provided withtransverse openings adapted to accommodate .movable blocks;shaft-supporting blocks mounted to slide and oscillate in the openingsin said harp-members; v springs supporting said blocks respectively; anon-rotatable shaft mounted in said blocks; a trolley wheel rotatable onsaid shaft; guard-plates connected with said harp-members respectivelyand adapted to limit outward movement of said shaft-supporting blocks;and contact springs connected with said harp-members respectively andadapted to limit inward movement of said shaft-supporting blocks, alsoadapted to maintain electrical connection between said trolley wheel andsaid harp.

3. ln a trolley, the combination of a harp having members provided withtransverse openings adapted to accommodate movable blocks;shaft-supporting blocks mounted to slide and oscillate in the openingsin said harpmembers; a shaft mounted in said blocks; a. wheel mounted torotate on said shaft; a contact spring on the inside of eachharp-member, limiting inward movement of the block in that harpmember,and maintaining electrical connection between the wheel and the harp; aguard plate on the outside of each harp-member, limiting outwardmovement of said block in that harpmember; and bolts respectivelyconnecting one contact spring and one guard plate with each harpsmember.

4. In a trolley, the combination of a harp having members provided withtransverse openings adapted to accommodate movable blocks; a contactspring on the inside of each harp-member; a guard-plate on the outsideof each harig-member; shaft-sup; porting bloc-lts between said guardplates and contact springs; springs supporting said movable blocks; ashaft mounted in said blocks; a trolley wheel rotatable on said shaft;and washers on said shaft engaged by said contact spring and engagingthe ends of the hub of said wheel.

ln witness whereof l have hereunto signed my name at Springfieldillinois this 2d day of June 1910.
